PANSLA ACQBEORA DN F :lIEW JERSEY- .J-Applicatiemfiled'jDecember18,1923. Serial No-681g315= T0v all whomz'tmwy concern:

Be it:known that I, .P-ERCY 1L. SIBOLE, a

citizen ofthe'United States, and residentof .Newark, in: the countyOfiESSQX and State; of

NewJersey, have invente'd certain new and useful :Improvements' inPrinting :Fresses, of whicln the following is; a specification.

This invention relates to improvements in printing machinesor pressesand has particular reference to improvements relating to the automaticpaper feeding attachment to job presses.

The object of the invention is to provide a novel, practical and simplemechanism for removing or detaching the paper feeding mechanism from thepress in order to make ready or to provide for manual feeding or forother purposes.

The prior art contains automatic feeders for job presses adapted to bemoved to one side of the press in order to accomplish any of theaforesaid purposes. Such constructions, however, necessarily require agood deal ofspace alongside the press, and this space serves noparticular purpose when the press is automatically operated.

This invention provides a construction whereby the paper feedinmechanism is lifted off the press and edevated directly above-the same,thus accomplishing the purpose of removability without requiring morespace than is necessary for the operation of the press. 7

The invention is disclosed in connection with a Chandler & Price pressequipped with I an automatic feeder of the Morrison type shown in U. S.Patent Number 1,476,829 dated December 11th,1923. 7

Referring to the accompanying drawings illustrating the preferred formof the invention Figure 1 is a side view of a printing press withautomatic feeder attachment embodying the invention, parts beingomitted, and

Figure 2 is a front view of the press looking from the left in Figure 1.

The printing press is identified by the frame 1, the platen 2 and theform meme her 3. On'the latter is suitably pivoted an arm 4- carrying asuction paper separating device 5 of the kind disclosed in the U. S.Patent Number 1,394,181, forseparating the topmost sheet of paper fromthe pile 6 resting on the paper support 7. The latter in turn is mountedon the feed table 8.

Reference is .made .-to tthe-patents aforesaid :for 13%]. completedisclosure .of the de- :tailed construction and operation of the paperfeed attachment. Foi' the-purposes of this invention, the paper feedtable-8 and paper support ;7 "represent the paper feed ech an sn theelement :5 being properly classified astaseparating device.

Referring i llOW Jnore particula'rly .=to the sub ect matter of thisinvention, the paper feeding mechanism aforesaid is supported on abracket 9 having shoulders 10 and 11 adapted to receive the feedingmechanism and whereby the same is properly registered or positioned onthe press. The bracket 9 i may be duplicated for the two sides of thepress, but preferably a smaller similar bracket 12 is used on the oneside, in this case the left side, as shown in Figure 2.

To the bracket 9 is secured a substantial foot piece 13 which supportsan upwardly inclined guide member 1a of any suitable form. At each endof the said guide memher is mounted a pulley or sprocket wheel 15 and 16over which pass a cable or chain 17. On the outside of the guide member1 1 a weight 18 is secured to the cable 17 while on the inside or theside facing the press,

there is secured to the cable a bracket 19. The latter is adapted togrip in under the feed table 8 to lift the same, see Figure 2, thebracket19 having a heavy lug 20 for this purpose. 21 is a handle forrotating the lower pulley 15.

During the normal operation of the press attachment, the feedingmechanism rests on the supporting brackets, as shown in full lines inthe drawings and the weight 18 is at the top of the guide member. Whenit is desired to remove the feeding mechanism,

' the pulley 15 is rotated whereby the chain is caused to move over thetwo pulleys and the bracket 19 lifts the feeding mechanism away from thepress. The weight of the feeding mechanism as it is lifted bodily abovethe press is counterbalanced by the weight 18. In this manner thefeeding mechanism may be raised to any height within the limit of thedevice and will remain at such height until, by reverse rotation of thepulleys, the feeding mechanism is lowered into operative relationshipwith the press, when the feeding mechanism will automaticallybe properlypositioned by the registering shoulders 10 and 11.

hen the feeding mechanism is elevated, the separating device 5 ispreferably first swung forward out of the way as indicated in Figure lin dotted lines of the arm 4.

It will be observed that the elevating device herein disclosed does notrequire any extra space alongside the press, and that when the feedingmechanism is elevated it. is completely out of the way and permits freeaccess to the press.

The structural details may of course, be altered and changed withoutdeparting from the principle of the invention and the scope of theappended claims.

I claim:

1. The combination with a printing press, of a paper feeding devicetherefor, mechanism for moving said device into and out of operativerelation with the press comprising upwardly extending guiding meanssecured to the press, a conveyor mounted in said guiding means, means onsaid conveyor engaging said feeding device for the purpose aforesaid anda handle for operating the conveyor.

2. The combination With a printing press, of a paper feeding devicetherefor, mechanism for moving said device into and out of operativerelation with the press comprising a guide member secured to the pressand extending upwardly in an inclined position in over the press, aconveyor mounted on said guide member, a bracket on said conveyoradapted to engage said feeding device to raise and lower the same and ahandle for operating the said conveyor.
